"Theplatform :3&1 preferably is made Vin .rectangularshape .but may be vmade in any other convenient shape within .the scope of the invention. .At the four. corners-of the platform inA diagonally-opposite positions are oppositely facing resilient supporting members .32. Preferably these are madefrom resilient `metal or other resilient material .into substantially S-shape .as vindicated in detail in Fig. '-5. The placing ofthe supporting members `32 .in vdiagonal positions in manner shown causes the members inadjacentcorners to be non-parallel andthereby provides lateral support in different .directions for the tab-le, yet permits ...theresilience of mounting needed to vaccomplish the objectives of the `invention. as will be better understoodas the description offthe invention proceeds. With the foregoing in'minoLrthe supportingmembers 32.1nay be .any suitable form providingnon-rigid support ofthe .table from the platform. The bottomplates .or surfaces .of `these supporting members are bolted or otherwise suitably secured .to thev platform 138, .witha slab of sponge Ir-ubber 313 orother cushioning means .between. .Although four supportstare illustrated, -a greater oraless numberscoulld be used aswell.

On. top ofwthe `upper lsurfaces-lor :platesf of the resilient .supportingLmembers 32 isv supported la tabledrmade of plywood -or otherstilflbut resillent material into rectangular shape, although it may be of any other suitable shape within the scope of this invention. A slab of sponge rubber 42 or other cushioning means is preferably inserted between the top plate and the bottom surface of the table 40 and those parts are then bolted or otherwise suitably secured together. By the means just described, the table 45 is mounted above the platform 30 in substantially parallel relation to, and in such fashion that the table 40 may have a considerable amount of the complex motion imparted to it, with practically none being transmitted to the base or support of the machine.

In Fig. 6 an alternative form of resilient support is illustrated which may be used as a substitute of the form illustrated in Fig. 5. In the form of Fig. 6 substantially U-shaped sheet metal members 36, 39 are joined by connecting bolts 31 with coiled springs 38 located around the shanks of the bolts between the under surface of the upper arm 39a of the lower member and upper surface of the lower arm 36h of the upper member. When this type of resilient support is employed, there is little or no need for other cushioning means between the support and the platform 40 and table 30. Various other types of resilient supports are possible for the purpose of avoiding transfer of the motion of the table to the platform.

The means for imparting the complex motion to the table 4U will now be described. Secured to the bottom surface of the table 40 are a pair of parallel bearing members 50 in which is rotatably supported a shaft 52 preferably lying parallel to a diagonal of the table 40. The bearing members may be secured to the table by bolts 54 or any suitable means. Adjacent each end of the shaft 52 are a pair of eccentrically mounted weights or members 55, 58. In order that as the shaft rotates these weights shall create a condition that will cause the jogging action of the table, it is necessary that the center of gravity of said weights be eccentric to the shaft axis; and the distance of the center of gravity relative to the shaft axis must be adjustable in order to vary the amplitude of motion.

In the embodiment of the invention. as illustrated herein, the pairs of weights at each end of the shaft are identical, and therefore they will be described together. They may be of substantially square section with an eccentrically located bore for the reception of the shaft 52, but obviously the weights may take other form. The weight 56 preferably is secured in semi-permanent relation upon the shaft 52 by set screws or bolts 53. It is desirable however, that the weight 58 be mounted by a more readily adjustable means and for this purpose the weight 58 has a neck 59, extending in a direction opposite the weight 56, and a large collar 6i) which is radially bored and screw-threaded to receive a manually operable thumb screw or bolt 62 whose inner end projects into a circumferential groove 55 cut into the shaft 52. Thus by loosening the thumb screw '52 the rotary position of the weight 58 (both on the shaft 52 and relative to the weight 55) may be readily varied, and the weight 58 may thereby be secured in any desired position of angular adjustment. With this structure and kind of adjustment it is possible to change the distance of the center of gravity from the axis of rotation and also to vary the relation of one weight to the other. When the weights are in the position shown'in Fig. 4 they will most nearly approach counterbalancing condition, the one to the other; but that condition will never be exactly reached, it being necessary at all times to have at least a minimum of unbalance and accompanying complex motion to have the machine perform its function of aligning and straightening sheets of paper within a stack. To provide for readily determining the position of minimum motion a pin 51 may be tted into the side wall of weight 56 in position to engage side edge of weight 58 (see Fig. 4). From that point the weight 58 may be angularly adjusted to increase the amount of such motion. Thus, on rotation of shaft and depending on the angular adjustment of the eccentrics in relationship to each other on the shaft, centrifugal forces are set up which produce an irregular wobble in the shaft and its bearings which is applied through its bearings to the table top, setting the table top in motion limited by the resiliency of the S-shaped spring supports 32. As the spring supports are compressed, they react to reverse this motion, and as the period of this reaction is quite different from that of its originating force, the rebound acts contra to the next periodic set of centrifugal impulses from the eccentrics, further complicating the direction, distance, and amplitude or acceleration of the motion of the table top.

In order to rotate the shaft 52, a pulley 10 is provided, preferably at the center of the shaft, and it is connected by a belt 'l2 with a second pulley 14 on the shaft of a conventional electric motor 16 which is bolted upon the upper surface of the platform 30. The feed wire 18 may connect the motor with an electric switch B conveniently located on the base or pedestal l0 and connected in any suitable fashion with the source of electric current.

From the foregoing it may now be understood that as the motor rotates, rotation of the shaft 52 is caused. The rotation of the shaft 52 with the weights located in any desired relation or position of adjustment will cause complex motion of the table 40 which is non-periodic and of variable intensity and of magnitude depending upon the position of adjustment of the weights and also speed of rotation.

While in a broad and general sense the motion of the table may be described as vibratory, the motion, more explicitly, may be described as follows:

The motion of any point in the table may be in all directions. Thus, a tendency of weight 56 to cause pure vibration in the narrow periodic sense of the word is complicated by the weight 58 which, acting at crosspurposes to weight 56, adds a separate independently acting force which may tend to move the table sideways or otherwise while the weight 56 is tending to move the table up or down. As a result, the actual motion of the table top, due to the S-shaped supports 32 and the opposed, adjustable eccentrics is a motion which is eccentric both in direction and rate. A

rpoint on the table top might at irregular intervals be at almost every possible point within a space dened by the amplitude of movement from its starting point.

Furthermore, adjustment of the weights at one end of the shaft differently than those at the other end will result in one side of the table having a different amount of degree of motion than the other, but both motions will be multi-directional. Thus, it is possible to handle simultaneously different weights of papers which may require different amounts of motion. Or, if the mattine@ table is `divided into more *than two parts, Cmore than two itypes of papers -may 'be -handled together. i

The ball and socket joint-(16,133,211) -1vvl'ii'chfenables the 'platformand table tobetilted-at any desired angle Aand also vin Yany ldirection ^`at Lwill, and which 'allows such tilting by C4merely overcomingthe friction of the joint with manual effort (without the need of loosening'and retigh-tening) y*is able tobe Vused because of `-tlie'nature and characteristics of operationof the i machine. Thatis to `say,'the'minimizing or in apractical sense, substantially eliminating 'transmission ff-to the platform thecomplex 'motions 'of `the table, en'ablesthe frictional vba'lland socket type df joint to be 'used when'tightening to provide nomore friction than can "be overcome manualy in tilting the table.V vThis combination of desirable characteristics Aand functions Iis "a definite improvement over "prior machines, A When thin sheets of 'tissue orlcarbo'n papers are to be aligned, `it -isdesirable "onfsmefocc'asions to rnaintainafilm` of air betweenthe sheets until their edges are in register. To'this end and to vmeet such conditions, I provide solid-sidewalls '44 around the table 40 so as to tend to retardthe escape of air from between the-successive sheets in the pile `orstac'k.

When 'heavier lsheets are to be stacked, the aligning is facilitated by providing a series of spaced posts 'around the vedge of the table 40.

-From theforegoing itwillbe .apparent that I have provided a structure which may'be constructed with comparatively ,inexpensive parts and requiring a minimum outlay of capital and i of labor and material. Yet the resulting machine is very`sturdy,has beenfou'ndvery reliable in use, requires a mini-mum -of attention and servicing over considerable periods, and embodies many improvements over prior machines.
